Rock Crusher, I am not sure where Nappanee is exactly, but if you ever get down towards Terre Haute, give me a shout. I shoot lefty, split finger as well and I reckon we could figure something out.
Just for the heck of it, try raising your nock point to 9/16" or 1/2". Set the brace height at 7 1/2" to 7 5/8" and see what you get. If you shoot three fletch, try shooting cock feather in, or rotate the nock until you have optimal feather clearance.
If you get down this way, drop me a pm and let me know you're comin'! Mike
